Abstract  The morphology and distribution of the antennal sensilla, of adult Aleochara bilineata and A. bipustulata (Coleoptera: Staphylinidae), important rove beetle predator-parasitoids of root flies, have been examined. The antennae of both sexes and both species are identical. A detailed ultrastructural study was conducted on the adult antenna of A. bilineata, on this basis, there are 3 main classes of olfactory receptors: basiconic sensilla in rimmed-pits, small basiconic pegs, containing 1-4 sensory dendrites, divided into 3 subclasses, and large basiconic pegs, containing a single dendrite. There are also 5 classes of mechanoreceptors; a single class of gustatory receptor, double-walled spoked hairs, non-porous sensilla, and coeloconic receptors of unknown function.
